pub fn content_type_guess_for_tree(root: &impl IsA<File>) -> Vec<GString>
Tries to guess the type of the tree with root

of content types, with the best guess coming first.
The types returned all have the form x-content/foo, e.g. x-content/audio-cdda (for audio CDs) or x-content/image-dcf (for a camera memory card). See the shared-mime-info specification for more on x-content types.
This function is useful in the implementation of

array of zero or more content types. Free with
